wrong calculate of some date

[sherafatian]

this package convert 1397/02/30 to 2018-05-20 that it's correct but convert 2018-05-20 to 1397/03/02 that means wrong. See my functions that do this:

function hijri2miladi($hijriDate) {
   $parseDate = date_parse($hijriDate);

   $miladi=jDateTime::toGregorian($parseDate['year'],$parseDate['month'],$parseDate['day']);

   $myDate = new DateTime();
   $myDate = $myDate->setDate($miladi[0], $miladi[1], $miladi[2])->format('Y-m-d');

   return $myDate;
}

And

function miladi2hijri($miladiDate) {
   $parseDate = date_parse($miladiDate);

   $shamsi = jDateTime::toJalali($parseDate['year'], $parseDate['month'], $parseDate['day']);
   $myDate = new DateTime();
   $myDate = $myDate->setDate($shamsi[0], $shamsi[1], $shamsi[2])->format('Y/m/d');

   return $myDate;
}

[morilog]

Your functions are wrong. You passed shamsi parsed arguments to DateTime constrcutor

>>> \Morilog\Jalali\jDateTime::toJalali(2018, 5, 20);
=> [
     1397,
     2,
     30,
   ]
>>> \Morilog\Jalali\jDateTime::toGregorian(1397, 2, 30);
=> [
     2018,
     5,
     20,
   ]
